Thank you all so much for your thoughts and suggestions. One thing I didn't mention is that the city of Dallas will not give us a permit so we are having to treat it like a building. This means we are going to be anchoring it with hurricane anchors on a nine inch cement slab. Any additional thoughts?

Safe as houses.... .

Well, now you're doubly sure it won't blow away or tip over.

Seriously, you're going to need that PE stamp on the permit; it's the city's CYA approach. They can easily size the anchors; in fact they prob. have prescriptive (following their directions and you're automatically ok) instructions for those units. It's the fear that the trailer will disassemble due to wind load that's more difficult to deal with...

If you can't find any 90 mph wind research, show them a picture of the Airstream that stood up well to the atomic bomb blast test in the 1950's!

Just wanted to thank you all for posting all of these responses. This is such a great community and i feel very welcomed in a place where i know very little! Ok -- so im throwing another doozie out there. We spoke with a structural engineer today. He asked the following questions:
- Height off ground?
- Locations of axles
- Does the sub-carriage (frame) have any locations or methods where a tie-down can be fastened? That is, how will we secure it to the ground or foundation. Where are they?

Does anyone out there know where i can find this info?

Thank you in advance for any and all thoughts. I'm overwhelmed by the community here.

There are a number of ways that an Airstream trailer can be secure to the ground with steel cables or chains.

Each side of the A-frame is a very good place to fasten to, along with both sides of the frame at the rear of the trailer.

You can also use a cable or chain around the outside of each axle just next to the axle mounting plate, and before the torsion arms.

For a tandem axle trailer, that would provide secure 8 places to fasten tie downs to.

Do not, attach anything to the axle tube or over it, between the side to side frame
area.

Cupcake girl you should look up the story on the mobile popcorn cart once used at Old City Park . . practically rebuilt it to 1500-lbs to meet "interpretation". This is not a new story in Big D. There was also an Airstream or Silver Streak used for years in Deep Ellum as a food concessionaire (early 90's). Reasonable concerns about fire are valid. Being protected from flying debris is something they cannot provide.

As to aerodynamics: low ground clearance (vital) and a radius that is 10% of the length on other edges is found to be valid for FE purposes. Winds pile on flat walls that aren't relieved by radiused edges. The upper portions -- and cross-section -- of an AS is excellent in this regard.

Volvo Trucks Magazine

Exterior shape and all metal framing are conducive to surviving 90 mph winds from any direction what with the shape provided. Wish we could say the same for power poles, directional signals, etc.

An F5 will eventually hit D/FW. But while being east of downtown Dallas is best (and slightly north), the concerns they have are valid. But grandfathered structures make it moot.

Sounds like time for a talk with your Council member.
